Description

Technical Field

[0001] The utility model relates to the technical field of plastics, in particular to a dehumidifying dryer for plastic processing and molding. Background Art

[0002] Plastic is a high molecular compound formed by polymerization of monomers through addition or condensation reactions. It has a medium deformation resistance, between that of fiber and rubber. It is composed of synthetic resin and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. The main component of plastic is resin. The basic properties of plastic are mainly determined by the nature of the resin, but additives also play an important role. Some plastics are basically composed of synthetic resins and contain no or little additives, such as plexiglass. Plastic products are usually made of plastic raw materials that are first granulated to form plastic particles. Plastic particles contain more water, so it is necessary to use a dryer to dry and dehumidify the plastic particles to ensure the processing quality of plastic products.

[0003] After searching, the existing Chinese patent announcement number is: CN218065815U, which provides a dehumidification dryer for plastic processing and molding. The patent sets two layers of sieve plates and sets the sieve plates at an angle, so that when the plastic particles are added into the drying box from the upper feed port, they will be screened through the two layers of sieve plates in turn. At the same time, the driving motor will also drive the two sieve plates to shake back and forth left and right, which is conducive to the plastic particle blocks on the sieve plates being dispersed into small particles when passing through the sieve plates, making it easier to dehumidify and dry the plastic particles.

[0004] Although the above patent can dehumidify and dry plastic particles, the above dehumidification dryer for plastic processing and molding still has the following problems: the patent only dehumidifies and dries the plastic particles through a fan, resulting in poor dehumidification and drying effect.
